You may want to collaborate on the design of such a thing with Martin Sustrik. Up until recently there was a repository filled with experimental code. One such experiment was a "super" ROUTER socket that included event notifications for things like connect/disconnect. I don't know how far Martin got with fleshing out that code, so it may have been more in the design phase than the implementation phase.
